WATCHCASE-PENDANT.

SPECIFICATION forming part of Letters Patent No. 69-1 ,412, dated January 21, 1902.

Application filed m 20, 1900.

To all whom, it may concern.-

Be it known that I, MICHAEL SPORLEDER, a citizen of the United States, residing in Colorado City, in the countyof El Pasoand State of Colorado, have invented an Improvement in Watchcase-Pendants, of which the following is a specification.

The invention relates to \ratchcase-pendants,-and has for its object the provision of certain improvements, as will more fully appear in the description hereinafter and the appended claims when taken in connection with the accompanying drawings, forming part hereof, wherein the preferable embodiment of the invention is delineated for the purpose of illustration.

The .invention has particular reference to I that class of pendants wherein the stem winding and setting devices are manipulated by a longitudinal and rotary movement of the stem. Heretofore in devices of this character it has been-the custom to establish communication between the winding or hand-setting mechanism through the medium of spring-pressed instrumentalities, and it is to obviate the necessity of such springs that the present arrangement has been devised.

The invention also embraces the idea of constructing a watchcase-pendant which will be practicallydust-proof, so that the admission of dust and the like, ordinarily so detrimental to the perfect operation of the watch, is effectually prevented.

The invention further relates to the provision of a construction of the character described whereby it will be practically impossible to accidentally throw the setting mechanism into gear, whereby the time might be rendered unreliable. 1

In the drawings like reference characters refer to corresponding parts in both views.

Figure 1 is a vertical sectional view of a pendant constructed in accordance with the present invention, parts being shown in elevation. Fig. 2 is a similar view of a slightlymodified form.

Referring more specifically to the drawings, A designates a tubular projection, which may be considered the body of the pendant, the same being rigidly connected to a wat'chcase of any ordinary or preferred construction.

B is the ring or bow, the respective ends of Serial No. 24,340. (No modelwhich are sprung into oppositely-arranged openings in the sides of an annular nut H. This bow may be riveted or otherwise firmly secured to the nut. The nut is interiorly screw-threaded at its respective ends and is adapted to engage corresponding external threads formed on the tube A.

E is a crown which is detachabl y connected, through the medium of screw-threaded engaging portions, with a stem D, designed to control the winding and hand-setting mechanism by being moved longitudinally in a manner to be hereinafter pointed out.

0 is the pendant-nut now in common use, which in its present adaptation is employed to control the movement of the stem D to set or wind the watch, as occasion may require. The inner surface K of the crown E and the enlarged or shouldered portion I of the stem D serve to limit the longitudinal movement of the stem, whichmovement in a huntingcase watch employing case-springs may be sufficient to allow the unlocking of the catchspring of the case.

The lower portion of the nut C, extending beneath the lower edge of the crown E, is milled or otherwise roughened, as at L, to constitute a gripping-surface to be engaged when it is desired to turn the said nut.

It being desirable that dust or the like be excluded from the interior or working parts of the watch, a screw t-hreaded seat is formed in the upper portion of the nut C adjacent the longitudinal opening therein, and in said seat a suitable packing n is clamped by a screw-threaded ringm in a manner to cause the same to bear upon the surface of the stem D, passing therethrough. It may be found desirable to facilitate the easy operation of the stem to saturate the packingn with a suitable lubricant.

The screw-thread in the pendant, adapted to receive the stem-controlling nut C, is pref.- erably a right-hand thread, While the external thread thereon adapted to receive the nut H, is a left-hand thread, and these respective threads are so arranged that in case the hand should accidentally come in contact with the pendant bow or ring or the stem-controlling nut C in the operation of winding'the watch by the crown E it will not loosen the annular nut H or said stem-controlling nut C.

The component parts of the pendant, as shown, occupy their normal relations, and the operation incident to setting and winding a watch may now be described as follows: To set the watch, the pendant bow or ring is grasped with one hand, while the other holds the watch. The bow is used after the manner of the wrench as a means for operating the nut H, to which it is firmly secured. The nut H being turned slightly to the left by the pendant-bow releases it from engagement with the lower edge of the stem-controlling nut C. The nut O is thereupon turned to the left by means of its milled edge L, which causes a longitudinal movement of the stem D in an outward direction. Thereupon the stem may be turned sufficiently to bring the setting-train into gear, when the crown E, secured to the stem, is rotated therewith independently of the nut 0, thereby setting the hands or indicators of the watch to the desired degree. The winding mechanism is throwniuto operation by steadying the crown E with the thumb and finger of one hand, while with the other hand the stem-controlling nut C is operated by its milled edge in a right-hand direction until the lower interior surface thereof is firmly seated on the upper edge of the pendant-tube A, after which the annular nut H is rotated in a right-hand direction through the medium of the pendant bow or ring until it sets firmly on the nut O and holds it in posit-ion, where itis normally retained to prevent any accidental movement of said nut in ordinary usage.

In the modified form shown in Fig. 2 the stem-controlling nut O is formed integral and constitutes part of the annular nut H of Fig. 1. This nut is preferably screw-threaded with a right-hand thread and simply screws onto the pendant-tube A in that'direction, and when seated thereon the pendant-bow, as in the former instance, should be parallel with the body of the case. The operation of setting and winding the watch with this particular construction is as follows: The pendant-bow, which is firmly secured to the stemcontrolling nut O, is turned with said nut to the left, the bow being used after the manner of a wrench. This movement of the nut C will carry with it in an outward direction the stem D and crown E, secured at the end thereof. The crown E and its stem may then be rotated independently of the nut O to set the hands or indicators of the watch. After this operation the crown is steadied with one hand while the other screws the nut 0 onto the pendant A through the medium of the bow or ring secured thereto, which will restore the parts to their normal positions.

It will be apparent that although special details of construction have been described in connection with the embodiments of this invention herein disclosed various changes may be made without departing in the least from the spirit of the invention.

Having thus described the invention, what is claimed as new, and desired to be secured by Letters Patent, is-

1. The combination with a pendant having an interior and an exterior thread, ofastem, a collar-nut secured on said exterior thread, a pendant-bow attached thereto, and a controlling-nut secured on said interior thread for holding said stem from accidental movement, substantially as described.

2. The combination with atubular pendant having a screw threaded portion, a stem adapted to be operated therein, anut engaging said screw-threaded portion adapted to overhang and abut directly against the end thereof, the upper part of the nut being adjacent the stem, and a crown secured to the stem and surrounding the upper end of the nut, substantially as described.

3. The combination with atubular pendant having a screw threaded portion, a stem adapted to be operated therein, a nut engaging said screw-threaded portion adapted to overhang and abut directly against the end thereof, the upper part of the nut being adjacent the stern, a crown secured to and surrounding the upper end of the nut, a seat in the upper inner portion of the nut, packing in said seat,and a clamping device for compressing said packing in said seat, substantially as described.

In testimony of which invention I have hereunto set my hand.

MICHAEL SPORLEDER.
